To aZZ w/wm, it may concern.-

Be it known that 1, WILLIAM E. MULHOL- LAN, a citizen of the United States, and a resident of Juneau, in the Territory of Alaska, have invented a new and Improved Camera Attachment, of which the following is a full, clear, and exact description.

The purpose of my invention is to provide a device which can be removably attached to any camera for the purpose of automatically operating the shutter at a predetermined time, enabling persons to take their own photographs from a point near to or at a distance from the camera.

A further purpose of the invention is to so construct a camera attachment of the character described that it may be adapted to the operating mechanism of any shutter whether the operating medium be a bulb, a push-button, or a lever-arm.

The invention consists in the novel construction and combination of the several parts,as will be hereinafterfully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indieate corresponding parts in all the figures.

Figure 1 is a perspective view of a camerabox and the attachment applied,the shutter of the box beinglever-operated. Fig. 2 is aplan view of the attachment. Fig. 3 is a bottom plan view of the attachment. Fig, i is a bot tom plan view of certain of the parts of the attachment. Fig. 5 is a perspective view of a camera-box and the attachment,the shutter of the box being operated by a push-button; and Fig. 6 is a perspective view of a camera-box and the attachment, the shutter being operated by a bulb.

The attachment consists of a casing A of suitable size in which a frame 13 is secured, carrying clockwork B of any approved type. The winding post 10 of the said clockwork extends out through the casing, and at the outer end of the post a hand or pointer 11 is secured, adapted to travel over a circular scale 12, having divisions 13 marked to indicate minutes or fractions thereof, a division 15 marked Stop, which when reached by the pointer indicates that the clockwork has stopped, and a division 15 marked Snap,

which when reached by the pointer indicates that the device has operated to snap the camera-shutter.

lVithin the frame 13 of the clockwork the winding-post 10 is provided with a stud 16 at right angles to said post. A lock-lever 17 is pivoted at its head 13 on the frame 13, and its body, which is free, ext-ends at one side of the Windingpost 10, as is shown in Fig. 3. The head 18 of the lock-lever at its outer edge where it joins the body is provided with an inclined shoulder 19, and a spring 20 bears at one end against the opposite side of the body of the lever, the opposite end of which spring bears against a pin 20 on the clockworkframe, and said spring normally holds the head 18 of the lock-lever-l? in receiving position.

At or near the free end of the body of the lock-lever 17 a crank-arm 21 is secured, which extends down and under the lever in direction of the winding-post 10, terminating in a foot 22, adapted at a suitable time to be engaged by the stud 16 of the winding-post to move the head of the lever from receiving position'and to release said head from the part with which it may be in locking engageinent.

At or near the winding-post 10 the inner end of a fixed arm 23 is secured to the clock work-frame, and this arm extends out a suitable distance beyond the casing. Opposite the fixed arm 23 the inner end portion of a second arm 2% is pivotally attached to the frame 13, adapted formovement to and from the fixed arm, being forced in direction of the fixed arm by a spring 2i" of suitable strength. ward from the casing usually as far as the fixed arm 23, and at its inner end is provided with a hook extension 25, terminating in an inward]y-directed lug 26,wh ich lug is adapted when the body of the arm 21 is forced against the spring an away from the fixed arm 23 to have locking engagement with the shoulder 10 011 the lock-lever 1'7. Said movable arm 2% is provided with a pin 26, extending from its inner face and located between the pivot of the arm and its outer end.

The casing A is attached to the camera-box G in any suitable or approved manner, preferably so that the casing can be removed at The movable arm 24 extends outwill, and when the shutter of the box (1 is operated through the medium of a lever 27, as is shown in Fig. 1, the outer end of the movable arm 24 is pivotally attached to the projecting end of the shutter-lever 27, usually through the medium of a crank-arm 28, while a similar crank-arm 28 is attached to the outer end of the fixed arm and is attached to the camerabox by a screw 29 or its equivalent, and this arrangement is practically all that is needed to hold the attachment in po sition on the box.

hen the arm 24 has been set and the proper time arrives to release the arm, the spring 24L" will act to force the arm 2st in direction of the arm 23, and thus move the shutter-lever 27 in a direction to manipulate the shutter for exposure.

lVhen the attachment is made to a camerabox having its shutter operated by a pushbut-ton 31, as is shown in Fig. 5, the attachment is so placed that the fixed arm 23 will be on the camerabox, while the movable arm 24 will be above the fixed arm and, as described, movable to and from the fixed arm. Preferably under this arrangement of the attachment it is secured to the camera-box by forming a U shaped projection 32 at the outer end of the fixed arm 23, the members of which projection extend one at each side of the push-button 31 and are provided with slots 33, which receive screws 34:, entered into the camera -box. Under this arrangement when the movable arm 24. has been set and has been released at the proper time it will be carried down upon the push-button 31 and will operate the same to operate the shutter for exposure.

\Vhen the shutter of the camera-box C is operated by a bulb 30, as is shown in Fig. 6, the device is so placed on the camera-box that the arms and 24 will extend in an upward direction, and after the movable arm 24 has been placed in locking position the bulb 30 is fitted in between the two arms ..3 and 2t, and when the proper time arrives to release the movable arm 24 said arm in its movement toward the fixed arm 23 will compress the bulb 30, and thus operate the shutter.

\Vhen the exposure has been made, an alarm is sounded. This is accomplished by placing a gong 35 in the cloclnvork-frame B, as is shown in Fig. 3, and providing a springhammer having an extension 37, which is en gaged by the pin 26 of the movable arm 24:, when the said arm is set and has passed by the said pin, so that when the arm 24c is forced inward by its spring 24- in its return passage by the projection 37 of the alarm-hammer it will'force the said hammer outward and cause the said hammer on its return to strike the gong 35 with sufficient force to sound an alarm.

In the operation of this device the pointer 11. is moved from Stop to any desired number on the scale4, for example, which would represent four minutes of timeand in thus moving the pointer 11 the windingpost is turned suffieiently to wind the main spring to set the clockwork in operation, and the stud 16 on the winding-post is removed. from the foot 22 of the angular arm 011 the lock-lever 17, enabling the movable arm to be carried away from the fixed arm 23, bringin the spur 26 at the hook end of the movable arm in locking engagement with the shoulder 10 on the lock-lever 17. The attachment is now set properly on the camera-box, and ii the clockwork does not start of itsell the device is shaken gently to start the same. The operator may now take a desired position near to or at a distance from the camera, and when the four minutes of time have elapsed the pointer 11 will have reached the wor( Snap and the stud 1.6 on the winding-post 10 will. have been brought in engagement with the foot 22 of the lock-lever 17, forcing the said lever against the tension of its spring 20 and carrying the head 18 of the lever out of engagement with the hook-section 25 of the movable arm 24, permitting the spring 2-11 of the said arm to act and force the arm 2i in direction of the fixed arm 23 to operate the shutter in either manner that has been described, and on the return movement of the said arm 24 an alarm is sounded, notifying the party that the picture has been taken. The clockwork will continue to run until the pointer reaches the word Slop on the scale or dial 12.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1..
